Rygchium madecasse de Saussure, 1852: 102 (key), 111, ♀ —“ Madagascar ” ( holotype MNHN).

Distribution. Madagascar: Antananarivo, Antsiranana, Fianarantsoa, Toamasina, Toliara ( de Saussure 1852, 1890; von Schulthess 1907; Giordani Soika 1941, 1999; Madl 1995; Gusenleitner 2000, 2004; Selis & Carpenter 2023) ( Fig. 63B View FIGURE 63 ).

Notes. The few available specimens show a wide range of variability, both morphological and chromatic ( Fig. 16 View FIGURE 16 ). The specimens coming from the eastern part of the island do not show any white pattern ( Fig. 16A View FIGURE 16 ) and have the metanotum protruding and with a clear transverse carina ( Fig. 16B View FIGURE 16 ), while the more western specimens have a narrow white band on T1 ( Fig. 16C View FIGURE 16 ) and the metanotum very little protruding, almost entirely oblique and with a very weak transverse carina ( Fig. 16D View FIGURE 16 ). A particularly interesting form is found in the Isalo National Park, which has larger size, a strongly protruding and carinate metanotum ( Fig. 16F View FIGURE 16 ), and tergites and sternites up to the fifth with evident white bands ( Fig. 16E View FIGURE 16 ). Some differences in sculpture are also observed, with larger specimens generally being more densely punctate. It cannot be excluded that these forms represent two or three distinct species, but the lack of males does not allow drawing of any conclusions in this regard.
